Project Overview
Thermosonics Pvt. Ltd. delivered a specialized acoustic engineering solution for a premium hospitality facility in Colva, addressing continuous noise generated by HVAC chillers, STP blowers, and backup diesel generator systems. The objective was to achieve environmental compliance while preserving equipment efficiency and guest comfort.
The Challenge
High operational noise from:
- 2 HVAC Chiller Units
- 2 STP Blowers
- 2 DG Sets
required a carefully engineered mitigation strategy. The key challenge was reducing noise without restricting airflow or increasing ambient temperature around critical equipment, which could lead to performance derating.
Engineering Solution
- Designed optimized acoustic barriers and sound attenuation systems
- Maintained thermal balance through controlled ventilation design
- Prevented heat accumulation around chillers
- Ensured compliance with Central Pollution Control Board (CPCB) guidelines
Scope Note: Noise barriers were installed up to the DG area. Kitchen exhaust systems were excluded from the project scope as per client requirements.
Measured Performance
Chiller Noise Barrier
- Before: 79.9 – 82 dBA
- After: 70 – 72 dBA
- Noise Reduction Achieved: 10 – 12 dBA
DG Noise Barrier
- Before: 73 – 75 dBA
- After: 56 – 59 dBA
- Noise Reduction Achieved: 16 – 19 dBA
Neighbouring Residential Area
Post-implementation measurements confirmed environmental noise levels below 55 dBA, meeting CPCB norms.
Project Impact
- Achieved regulatory-compliant noise levels
- Reduced disturbance to surrounding community areas
- Maintained HVAC efficiency through thermal-acoustic balance
Delivered a sustainable and performance-focused engineering solution
